I walk into work one day and a colleague says ‘That tie doesn’t go with that shirt.’ I learn something, and my behaviour changes. Was that comment ‘learning content’?

The point, of course, is that there is no such thing as learning content – micro or otherwise. There is just learning and content: we learn, and whether or not a piece of content helps us to learn, helps us not to learn, or is merely useless depends entirely on the context. In general, our learning is driven by the challenges we face, not by content.
